- This invention relates to a rotator for a dish washing machine; and itis an improvement on the washing machine `disclosed in the a plicationfor United States Letter Patent led J anuary`30, 1929, Serial Number336,069.

f The princi al object of this invention is -to improve t e rotator ofthe washing machine so it is more simple to construct andl assemble andwhich is more eiiicient in picking up the liquid from the bottom ofthereceptacle and discharging it with great force lupwardly into a chamberin which the articles to be cleansed are located.

l5 Features of invention are shown in the-construction, combination andarrangement of' the spaced disks and associated parts whereby a rotatoris provided that is eas to construct, assem'ble andoperate; whic Y alsois eiiective to pick up the water` below the longitudinal axis of therotator shaft and thrpw A it lradially above the shaft. Other objects,advantages and features .of invention may appear from the accompany- 5ing drawings, the subjoined detailed description and thev appendedclaims.

The `accompanying drawings 'illustrate the Fig. 2, showin the doors inclosed position and also showlng a side viewoir the rotators and motor;and baskets of dishes in each upper 'chamber.

The washing machine includes a receptacle formed of a bottom 10, endwalls 11,

v12, a' center wall 13 and sidek1 walls 14 15 30,

that 'e 1scured together `and supported on y he side wa11s.14, 154 areextended upward abovethe end and center walls, and are secured togetherby a/'top plate 18, which, to- 85 -gether with the sliding end doors 19,20 and v s lidng center doors 21, 22 form upper chain l bers into whichwire baskets l23 containing dishes 24 can be extended and. supported on90 angle irons ,26 secured to the end walls 11 i v and 12 and centerpartition y13, and theslats are spaced a considerabledistance apart so95 that liquid 31 can be thrown-from the lower v chambers 29, `throughthe partition into the upper 'chambers 32, 33 so as to washand rinse thedishes in the baskets.y The forego- -ing parts are all old except' therotators and 190 are shown only for the purpose of illustrating theoperation of the rotators.

The rotators 27, 28 are constructed and operated alike. Each includes anumber of disks 34 that are secured on a shaft 35 having its endsjournaled in the end walls 11, 12 and extended through the center wall13 of the machine, as indlcated in Fi s. 1 and 3, The disks 34 arespaced from t e walls 11, 12 and 13 by washers 36, and are spaced apartfrom one another by the scoops 37 and radial arms 38. The outer ends ofthe arms 38 are bent into cylindrical sleeves 39 throughwhich the tierod bolts 40 are extended, and these rods also extend through holes 41in the 'disks 34and are secured in place by nuts 42.

- bearing around the shaft to pinchingly engage it so that they rotatetogether.

If desired the shaft 35 can be square, as shown in Fig. 11, in whichinstance the center openings 45 in the disks 45 would also be squared tolit it.

The disks 34 are formed of sheet metal blanks, as indicated by therectangle enclosedby the dotted lines 46. These disks are cut out ofthemetal blanks so that each has the scoops 37 v integral with theperipheral edges of the disks; and these scoops are then bent over sothat theyv extend at right angles 'to the disks.

Each scoop 37 is provided with an integra-l flange 47 that extendsrearwardly and terminatesyin a tail piece 48 that is secured by rivets49 to the disk, each disk beingprovided with spaced rivet holes 50 forthat purpose, as shown best in Figs. 6 and 10. f

A plain disk 51 is arranged at the terminal end-of each rotator and theyare the same diameterV and formed like the other 'the scoops disks'except that they do not carry the scoops 37, see Figs. 3 and 8.

The scoops 37 are arranged so that when the shaft 35 is rotated theywill pick up a charge of the liquid 31 as they enter it and.

force is inwardlytoward the -axis of the shaft' into the spaces betweenthe inside of and the rear side of the radial arms; and when the scoopsare turned to a position clear of the bod the charges begin to disc argeby centrifu gal force from the spaces between the front sides of theradial arms andthe rear sides of the scoo asy illustratedby theshortarrows'in ig. 9. j,

The liquid 31 either 'for washing or rinsing the dishes 24 is filledintothe lower cham'- bers'29, 30 until it reaches a level slightly abovethe shaft 35; 'and the scoops of the rotatrs are arranged so that whenin operation the up 'substantially all of the liquid harge it into theupper chambers '32,

of the liquid 31.

33, it being understood that the rotators 27 and 28 are driven at highspeed so that they pick up the liquid very rapldly and throw it withgreat force into the upper chambers.

The shaft 35 is driven by a motor 52 secured by bolts 53 tothe bottom`10 and it is connected to the shaft 35 by a chain drive 54 enclosed inthe housing 55, as indicated in Figsl, 2 and 3.

Platforms 56 57 are secured to the ends of the washing machinel tofacilitate placing baskets of dishes in and removing them from themachine, and the doors are provided with handles y58, 59, 60, 61 so theycan be raised or lowered when necessary.

In operation the lower chamber 27 is charged with a liquid solutionsuitable for washing dishes, and also the chamber 30 is charged with aliquid suitable for rinsing them after they are washed. Then the 'door19 is opened and a wire basket filled with soiled dishes is laced on theslat partition 25, in the cham er 32, and the door again closed.

Then the motor 52 is started and driven until the dishes in chamber 32are thoroughly washed. Then the doors 19, 21 and 22 are opened and the.basket of washed dishes is moved into the chamber 33, and another basketof soiled dishes is placed .in chamber 32. Then with the doors closed,ythe motor is again started to wash the dishes in the chamber 32, andrinse the dishes in the chamber 33. Then when these baskets of dishesare properly treated all the doors of the machine are opened so that thebasket of rinsed dishes can be removed and the washed dishes transferredfrom the chamber 32 to chamber 33,

'so another basket of soiled dishes can be placed in the chamber 32.Then/allthe ed to re eat Lthe rocess of washing and rinsing bas ets ofishes in successive order as described. l
